Merge branch 'pm-cpufreq' 

* pm-cpufreq: (23 commits)
  cpufreq: Register drivers only after CPU devices have been registered
  cpufreq: Add NULL checks to show() and store() methods of cpufreq
  cpufreq: intel_pstate: Fix plain int as pointer warning from sparse
  cpufreq: sun50i: Fix CPU speed bin detection
  cpufreq: powernv: fix stack bloat and hard limit on number of CPUs
  cpufreq: Clarify the comment in cpufreq_set_policy()
  cpufreq: vexpress-spc: find and skip duplicates when merging frequencies
  cpufreq: vexpress-spc: use macros instead of hardcoded values for cluster ids
  cpufreq: s3c64xx: Remove pointless NULL check in s3c64xx_cpufreq_driver_init
  cpufreq: imx-cpufreq-dt: Correct i.MX8MN's default speed grade value
  cpufreq: vexpress-spc: fix some coding style issues
  cpufreq: vexpress-spc: remove lots of debug messages
  cpufreq: vexpress-spc: drop unnessary cpufreq_arm_bL_ops abstraction
  cpufreq: merge arm_big_little and vexpress-spc
  cpufreq: scpi: remove stale/outdated comment about the driver
  ARM: dts: Add OPP-V2 table for AM3517
  cpufreq: ti-cpufreq: Add support for AM3517
  ARM: dts: omap36xx: using OPP1G needs to control the abb_ldo
  cpufreq: ti-cpufreq: omap36xx use "cpu0","vbb" if run in multi_regulator mode
  ARM: dts: omap3: bulk convert compatible to be explicitly ti,omap3430 or ti,omap3630 or ti,am3517
